2019 Pacific League Climax Series
The Final Stage was a best-of-six series hosted by the Lions. Having won the regular season, Seibu was awarded a one-win advantage over the Hawks. The series was played between October 9 to 13. SoftBank swept Seibu 4–1 in four games to advance to the 2019 Japan Series, where they competed against the 2019 Central League Climax Series winner, the Yomiuri Giants.


2019 Pacific League Climax Series, First Stage
The Fukuoka SoftBank Hawks clinched a postseason berth on September 19, their sixth straight. After failing to overtake the Lions in the final week of the season, the Hawks were ensured home field advantage in the First Stage of the Climax Series. The Tohoku Rakuten Golden Eagles clinched a third-place finish and a spot in the Climax Series on September 24. It was their first postseason appearance in two years. The Hawks were 13–12 against the Eagles during the regular season.


2019 Pacific League Climax Series, First Stage, Game 1
The Eagles quickly took the lead in the top of the first inning with a solo home run by Hideto Asamura off of Hawks' starting pitcher Kodai Senga. SoftBank quickly responded in the bottom of the same inning with a solo home run of their own by Kenta Imamiya off of Eagles' starter Takahiro Norimoto. In the bottom of the next inning, Seiichi Uchikawa's two-run home run gave the Hawks the lead. However, Rakuten continued to score and eventually took the lead after three solo home runs in three separate innings: the third, fifth and seventh.


2019 Pacific League Climax Series, First Stage, Game 1
In the top of the ninth inning, Hiroaki Shimauchi walked and then advanced to third base after a wild pitch and a throwing error. Asamura gave the Eagles an insurance run when he singled to drive Shimauchi home, the only run in the game scored via a method other than home run. Eagles closer Yuki Matsui retired all three Hawks' batters in the bottom of the ninth inning to record the save.


2019 Pacific League Climax Series, First Stage, Game 2
After the Eagles scored a run in the top of the first inning, the Hawks again followed suit, tying it up in the bottom of the inning via Yuki Yanagita's solo home. In the bottom of the third, Yanagita again tied the game with an RBI double after Asamura hit a solo home run in the bottom of the inning. Alfredo Despaigne' two-run homer later that same inning briefly gave the Hawks the lead. After Hawks starter Rick van den Hurk was removed with two outs in the forth inning, reliever Shinya Kayama walked two batters.


2019 Pacific League Climax Series, First Stage, Game 2
Asamura then tied it up by singling in two runs in the fourth, collecting two more RBIs. Shuhei Fukuda broke the 4–4 tie with a solo home run in the bottom of the fourth inning, putting the Hawks ahead for good. They added an insurance run in the fifth when Despaigne singled in Yanagita. The Hawks bullpen kept the Eagles scoreless from the fifth inning on to secure the win.


2019 Pacific League Climax Series, First Stage, Game 3
Unlike the previous two games in the series, scoring in Game 3 didn't start for either team until the fourth inning. Eagles' and Hawks' starting pitchers Takayuki Kishi and Rei Takahashi, respectively, kept both teams scoreless through the first three innings. Rakuten's Asamura scored the first run of the game with a solo home run in the top of the fourth. He homered in all three games and hit four home runs in total in the series. Kishi had not allowed a hit until giving up back-to-back singles to Despaigne and Yurisbel Gracial in the bottom of the inning.


2019 Pacific League Climax Series, First Stage, Game 3
Seiichi Uchikawa then tied the game by driving in a run. The tie continued until the seventh inning, when Uchikawa homered off of Rakuten reliever Sung Chia-hao to give the Hawks the lead. The Hawks couldn't breakthrough in the remaining innings with SoftBank reliever Liván Moinelo and closer Yuito Mori keeping them scoreless to allow the Hawks to win and advance to the Final Stage of the Climax Series.


2019 Pacific League Climax Series, Final Stage
The Saitama Seibu Lions clinched the Pacific League pennant, their second straight, on September 24. The title also insured that the Lions would be awarded both a one-game and home field advantages in the Final Stage of the Climax Series. At the end of the season, the Lions battled the Fukuoka SoftBank Hawks, who finished the season only two games behind, for the league title. This Final Stage series was a rematch of last year's PLCS Final Stage series in which the Hawks defeated the pennant-winning Lions to advance to the Japan Series. During the regular season, Seibu went 12–13 against the Hawks.


2019 Pacific Northwest measles outbreak
In early 2019, a measles outbreak occurred in the Portland metropolitan area, including the Clark County, Washington suburbs, in the United States. At the time, the outbreak was the largest outbreak in more than two decades; outbreaks in 2019 in areas including Brooklyn  and Rockland County, New York have since seen far greater numbers of cases.


2019 Pacific Northwest measles outbreak, Background
In late December 2018, the Public Health Department of Clark County, Washington identified a patient with a high fever and rash, which are symptoms characteristic of measles. This was Clark County's first confirmed case of measles. The case sparked immediate concern, as measles is a highly contagious disease: the virus can spread through coughing or sneezing, and it is infectious enough that 90% of people in close proximity to the patient, if unvaccinated, will contract measles. Measles is also highly contagious because, for up to two hours, it can live on both surfaces and in airspaces.


2019 Pacific Northwest measles outbreak, Background
The area where the outbreak began and spread is considered an anti-vaccination hotspot. In Clark County, the measles vaccination rate was 78% at the time of the outbreak, too low for effective herd immunity. The outbreak, which has struck mostly voluntarily non-immunized children, may have started at a Vancouver, Washington church attended by largely immigrant parents "who don't trust government – or vaccination programs" after residing in the former Soviet Union. The virus was reintroduced to the Pacific Northwest in December 2018 by an "international traveler" entering Clark County.


2019 Pacific Northwest measles outbreak, History and progression of outbreak
Through the end of December 2018 and into January 2019, the number of measles cases in Clark County continued to increase, even after patients were placed in quarantine environments. Clark County public health officials identified that one of the measles patients from Oregon had been previously traveling through the Portland International Airport on January 7, which may have been related to more recent measles cases identified in the following weeks located in the states of California, Colorado, Connecticut, Georgia, Illinois, New Jersey, New York, Oregon, Texas, and Washington that emerged throughout January 2019.


2019 Pacific Northwest measles outbreak, History and progression of outbreak
On January 4, 2019, the Clark County health department advised the public that one case had been detected, and on January 15, two more were confirmed. On January 18, 2019, with 19 known cases of measles, Clark County officials declared a health emergency. On January 25, with 30 cases reported, Washington governor Jay Inslee declared a statewide medical state of emergency in response to the "extreme public health risk" and called on the Washington Military Department to assist. By January 28, 36 cases had been reported, one of which was in the Seattle area.


2019 Pacific Northwest measles outbreak, History and progression of outbreak
Two children visiting Hawaii from the outbreak area, who had not been vaccinated and developed the disease, were quarantined on the Big Island in late January. By January 30, 40 cases had been confirmed. By January 31, there were 43 confirmed cases and the state of North Dakota sent a medical response team to aid the Northwest. By February 15, 53 cases had been identified, 47 in non-immunized individuals. By February 24, 65 cases had been confirmed in Clark County. By March 18, the number of confirmed cases reached 73.


2019 Pacific Northwest measles outbreak, History and progression of outbreak, County public health emergency and statewide state of emergency
On January 18, once 19 measles cases had been identified, a public health emergency was declared throughout Clark County, Washington by Eileen Quiring, the Clark County Council Chair. This public health emergency was declared to allow the county to access public health resources outside of those available in Clark County, as well as to raise public awareness about the outbreak to encourage citizens to take necessary health precautions.


2019 Pacific Northwest measles outbreak, History and progression of outbreak, County public health emergency and statewide state of emergency
On January 25, a state of emergency was declared throughout the entire state of Washington by Governor Jay Inslee. In the official proclamation, Governor Inslee stated that "the existence of 26 confirmed cases in the state of Washington creates an extreme public health risk that may quickly spread to other counties".

Inslee's concluding point discussed the implications of the outbreak for the well-being of the state itself: "The measles outbreak and its effects impact the life and health of our people, as well as the economy of Washington State, and is a public disaster that affects life, health, property or the public peace."


2019 Pacific Northwest measles outbreak, Personal belief exemptions
None of the 59 patients identified as of February 16, 2019 had received their complete set of two MMR (measles, mumps, rubella) vaccinations. Proper protection against measles, mumps, and rubella is best secured when children receive their first of two vaccine doses at 12 to 15 months of age, and their second dose between ages 4 to 6 years old. According to the Center for Disease Control, 91.9% of children aged 19 to 35 months had received at least one dose of the MMR vaccine in the year 2017.


2019 Pacific Northwest measles outbreak, Personal belief exemptions
For the 2017–2018 academic year in Clark County, personal belief exemptions were filed on behalf of 7.9% children enrolled in school (kindergarten through grade 12). Personal belief exemptions (PBE) are forms that can be filled out by parents that excuse children from school-wide immunization requirements on the premise of moral, philosophical, or religious opposition. Only four of the 50 United States prohibit the utilization of PBEs entirely: Mississippi, West Virginia, California, and most recently in June 2019, New York. 18 states, including Oregon and Washington, however, allow individuals to opt out of vaccinations for themselves and/or their children on the premise of conflicting religious, moral, or personal beliefs. There is a direct positive correlation between strictness of state vaccination laws and rates of vaccination among states.


2019 Pacific Northwest measles outbreak, Public response
As the measles outbreak grew, news coverage expanded across the country about not just the outbreak itself, but whether or not state or government mandated vaccination policies could have prevented its spread. According to Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine, the Pacific Northwest is home to an outspoken population of anti-vaccination lobbyists that are likely in part responsible for the increased prevalence of personal belief exemptions throughout the region.


2019 Pacific Northwest measles outbreak, Public response
Despite the area's relatively low immunization rates, health officials have observed a recent spike in the number of people throughout Washington and Oregon interested in receiving a measles vaccine. Public health administrator Shawn Brennan, an employee at Sea Mar Community Health Center in Vancouver, Washington explained that the increased public concern had pushed the clinic to order nearly 10 times as many vaccine doses than average.


2019 Pacific Northwest measles outbreak, Public response
Press coverage regarding the Pacific Northwest measles outbreak fostered nationwide interest in the spread of the disease. The topic "measles" was the most searched it had ever been in the United States since the 2015 Disneyland outbreak, according to Google Trends. With the identification of more cases, public outrage continued to grow as the Washington Department of Health disclosed that, as of February 21, 2019, over one million dollars had been spent on the outbreak, largely to cover the costs of medical supplies and staff. “This is taxpayer money for something that could have been completely, utterly preventable in the first place,” explains Clark County public health director Alan Melnick, in reference to the MMR vaccine designed to prevent the spread of measles.


2019 Pacific Northwest measles outbreak, Public response
In the past decade, epidemiologists have linked decreased immunization rates to the increasing prevalence of social media. The Internet is the primary vessel in which misinformation about health consequences of vaccinations is spread, most of which is in relation to Andrew Wakefield’s study linking the MMR vaccine to the development of autism that has since been discredited by the CDC.


2019 Pacific Northwest measles outbreak, Public response
Social media platforms have taken their own individual efforts to prevent the dissemination of false information. As of September 2018, Pinterest had banned users from searching for content about vaccines. In January 2019, Facebook announced that it will be banning posts promoting anti-vaccination propaganda, and the website will no longer be suggesting anti-vaccination pages or groups for users to join. In February 2019, YouTube stated that any user or channel endorsing anti-vaccination content will be demonetized entirely, and not receive any funding for advertisements played before videos.


2019 Pacific hurricane season
The 2019 Pacific hurricane season was a near average season which produced nineteen named storms, though most were rather weak and short-lived. Only seven hurricanes formed, the fewest since 2010. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.


2019 Pacific hurricane season
The season had a rather slow start, with no tropical cyclones forming in the basin during the month of May for the first time since 2016, and the first time that no storms formed before the month of June since 2011. The season became the latest-starting Pacific hurricane season on record since reliable records began in 1971 with the first tropical depression, which eventually became Hurricane Alvin, forming on June 25.


2019 Pacific hurricane season
The strongest hurricane of the season, Barbara, formed on June 30 and peaked as a high-end Category 4 hurricane on July 3. August was extremely quiet with no hurricanes forming during the month, a first for a season since 1973. September was much more active with six systems developing, of which three became hurricanes. Activity decreased appreciably in October and November as most of the storms remained weak and short-lived.


2019 Pacific hurricane season
Land impact was relatively minimal. The remnants of Barbara caused power outages in Hawaii in early July. Hurricanes Erick and Flossie both threatened Hawaii, but the systems weakened significantly before reaching the islands, both causing minimal effects. Tropical Storm Ivo and Hurricane Juliette both brought strong winds to Clarion Island. In late September, Hurricane Lorena made landfall in southwestern Mexico and Baja California Sur, and its remnant moisture entered the southwestern United States. Lorena was responsible for one death and damages worth $910,000. Tropical Storm Narda took a nearly identical track a week later, killing six and causing $15.2 million in damage. Overall, this season was drastically less active and destructive than the previous year, causing about $16.1 million in damages and seven fatalities.


2019 Pacific hurricane season, Seasonal forecasts
On May 15, 2019, the Servicio Meteorológico Nacional (SMN) issued its first forecast for the season, predicting a total of 19 named storms, 11 hurricanes, and six major hurricanes to develop. On May 23, the National Oceanic and Atmospheric Administration released its annual forecast, predicting a 70% chance of a near- to above-average season in both the Eastern and Central Pacific basins, with a total of 15–22 named storms, 8–13 hurricanes, and 4–8 major hurricanes.


2019 Pacific hurricane season, Seasonal forecasts
The reason for their outlook was the forecast of an El Niño to continue through the season, which reduces vertical wind shear across the basin and increases sea surface temperatures, favoring increased tropical cyclone activity. In addition, many global computer models expected a positive Pacific decadal oscillation (PDO), a phase of a multi-decade cycle that favored much warmer than average sea surface temperatures that had been ongoing since 2014 to continue, in contrast to the 1995–2013 period, which generally featured below-normal activity.


2019 Pacific hurricane season, Seasonal summary
The season officially began on May 15 in Eastern Pacific and on June 1 in Central Pacific; both ended on November 30. Initial activity was slow, with the first tropical depression forming on June 25. The strongest storm of the season, hurricane Barbara, reached peak intensity on July 2 as a high-end category 4 hurricane. The season became more active in July, with five tropical cyclones forming, including two storms that intensified into hurricanes. Among them was Hurricane Erick, which reached Category 4 status on July 31. This level of activity came to a halt in August, with only three named storms forming, none of which reached hurricane strength.


2019 Pacific hurricane season, Seasonal summary
On the first day of September, Hurricane Juliette formed, becoming the third major hurricane of the season. Moreover, tropical activity also began in the Central Pacific with the formation of Tropical Storm Akoni on September 3, which dissipated two days later. There were no tropical cyclones for five days until the formation of Hurricane Kiko on September 12 and the formation of Tropical Storm Mario and Hurricane Lorena five days later. In late September, Tropical Storm Narda became the sixth named storm to form during the month, tying the record for the most active September with the seasons of 1966, 1992, 1994, 1997, 2001 and 2005.


2019 Pacific hurricane season, Seasonal summary
Three tropical storms formed in the month of October, the first one was Tropical Storm Ema which formed on October 12 in the Central Pacific, becoming the first such occurrence since 2016 in which more than one tropical cyclone was named in the basin. The second named storm of the month, Octave, formed on October 17 and dissipated two days later without threatening land. Priscilla formed on October 20 and later dissipated the next day while it brushed Western Mexico. In mid-November, Tropical Storm Raymond formed on November 15, just fifteen days before the season officially ended.


2019 Pacific hurricane season, Seasonal summary
The accumulated cyclone energy (ACE) index for the 2019 Pacific hurricane season was 83.56 units in the Eastern Pacific and 14.4275 units in the Central Pacific. The total ACE in the basin is 97.9875 units.


2019 Pacific hurricane season, Systems, Hurricane Alvin
A tropical wave moved off Africa's western coast on June 12, reaching the Caribbean Sea a week later and continuing across Central America. The wave spawned an area of low pressure on June 24, and this feature organized into the season's first tropical depression by 12:00 UTC on June 25 while located a few hundred miles south of Mexico. The depression initially struggled to organize, but it eventually intensified into Tropical Storm Alvin around 12:00 UTC on June 26. As a mid-level ridge steered the storm west, it began to organize in a more favorable environment.


2019 Pacific hurricane season, Systems, Hurricane Alvin
After very deep convection fired over its center, Alvin became a minimal Category 1 hurricane by 00:00 UTC on June 28 as it developed a 10 mi (16 km) diameter eye. After attaining peak intensity, the system encountered cooler waters and increasing wind shear, causing it to weaken. Alvin became devoid of deep convection by 06:00 UTC on June 29, degenerating to a remnant low to the west-southwest of Baja California Sur at that time. The remnant low drifted west and dissipated around a day later.


2019 Pacific hurricane season, Systems, Hurricane Barbara
Less than a week after a tropical wave spawned Alvin, a new tropical wave moved off Africa on June 18. It remained disorganized while crossing the Atlantic, and it progressed into the eastern Pacific on June 26. The disturbance organized over the coming days and developed into Tropical Storm Barbara by 06:00 UTC on June 30, having already possessed gale-force winds at the time of formation. It moved quickly westward while struggling to intensify in an environment of wind shear and dry air. By July 1, however, more favorable environmental conditions allowed the storm to intensify.


2019 Pacific hurricane season, Systems, Hurricane Barbara
Barbara became a hurricane by 18:00 UTC on July 1 and began to rapidly intensify, ultimately reaching its peak at Category 4 intensity with winds of 155 mph (250 km/h) at 00:00 UTC on July 3. The storm maintained a 15 mi (24 km) diameter eye surrounded by an intense central dense overcast and numerous rainbands at that time. A turn toward the northwest brought the storm into cooler waters and drier air, with an increasingly rapid rate of weakening through July 5. Barbara degenerated to a remnant low by 00:00 UTC on July 6 after losing its deep convection. The low turned west and dissipated into a trough on July 8 to the east-southeast of Hawaii.


2019 Pacific hurricane season, Systems, Hurricane Barbara
Barbara's remnants passed 120 mi (190 km) south of Hawai'i on July 8, producing showers over the windward regions of the island and nearby Maui. The storms generated by Barbara's remnants were cited by Hawaiian Electric Industries as the likely cause of power outages affecting 45,000 electricity customers.


2019 Pacific hurricane season, Systems, Tropical Storm Cosme
Another tropical wave moved off Africa on June 23 and crossed into the East Pacific on July 2. The favorable influence of a kelvin wave and the Madden–Julian oscillation allowed the disturbance to organize, and it developed into Tropical Storm Cosme by 12:00 UTC on July 6. Anomalously strong high pressure aided in accelerating the storm's winds, and it attained a peak intensity of 50 mph (80 km/h) upon formation. Thereafter, cooler waters, dry air, and wind shear arrested Cosme's development, and the cyclone began to weaken while turning northwest. By 00:00 UTC on July 8, Cosme degenerated to a remnant low. The low later turned west before dissipating into a trough early on July 11.


2019 Pacific hurricane season, Systems, Tropical Depression Four-E
The tropical wave that spawned Cosme was succeeded a week later by another. It entered the East Pacific on July 8 but remained disorganized for several days while tracking west. The wave gave way to an area of low pressure on July 12, which then organized into a tropical depression only six hours later. The depression was located over very warm sea surface temperatures but under the influence of moderate wind shear, preventing organization. By July 12, persistent upper-level winds began to shear away the cyclone's convection. It degenerated to a remnant low at 00:00 UTC on July 14 while located south-southwest of Baja California Sur. The low produced intermittent bursts of convection as it moved west-northwest but ultimately dissipated early on July 15.


2019 Pacific hurricane season, Systems, Tropical Storm Dalila
A tropical wave moved off Africa on July 8, showing some signs of organization until it reached the western Caribbean. It continued into the East Pacific and formed a tropical depression around 06:00 UTC on July 22. The cyclone remained disorganized for much of its duration, plagued by northerly wind shear and cooler waters. However, the formation of spiral rai bands allowed it to become Tropical Storm Dalila by 06:00 UTC on July 23; the storm attained peak winds of 45 mph (70 km/h) six hours later. It progressed over even cooler waters, causing Dalila to become a remnant low by 12:00 UTC on July 25. The low drifted west and dissipated the following day.


2019 Pacific hurricane season, Systems, Hurricane Erick
Erick originated as a tropical wave that emerged off the coastline of Africa on July 12. It entered the eastern Pacific in late July, where convection blossomed in the presence of a very strong kelvin wave. Moderately wind shear slowed the formation process, but a tropical depression finally developed around 12:00 UTC on July 27 and organized into a tropical storm six hours later. Dry air and the elongation of its center likewise slowed organization shortly after development, but a center relocation placed the storm in a favorable environment.


2019 Pacific hurricane season, Systems, Hurricane Erick
Erick intensified into a hurricane at 18:00 UTC on July 29 and began a period of rapid intensification, intensifying to 60 mph (95 km/h) in just 24 hours as it crossed into the central Pacific basin. This bout of strengthening brought Erick to its peak as a Category 4 hurricane with winds of 130 mph (210 km/h) around 18:00 UTC on July 30. The cyclone subsequently weakened while passing south of Hawaii as wind shear increased over the system. Bursts of convection allowed Erick to persist as a tropical cyclone from August 3 to 4. However, the system eventually degenerated to a remnant low by 00:00 UTC on August 5. The remnants of Erick continued moving west and reached the International Date Line on August 8.


2019 Pacific hurricane season, Systems, Hurricane Flossie
A tropical wave moved off Africa on July 16 and crossed into the East Pacific eight days later. The disturbance coalesced while positioned south of Mexico, organizing into a tropical depression by 12:00 UTC on July 28. It slowly intensified while moving rapidly west-northwest, becoming Tropical Storm Flossie early on July 29 and a hurricane later the next day. After attaining peak winds of 80 mph (130 km/h), the storm weakened amid increasing westerly wind shear. These unfavorable upper-level winds abated on August 1, causing Flossie to fluctuate in intensity for the next day. By August 3, however, the storm embarked on a gradual weakening trend. It degenerated to a remnant low to the north of Hawaii at 00:00 UTC on August 6. The low turned north-northwest and dissipated the next morning.


2019 Pacific hurricane season, Systems, Tropical Storm Gil
On July 28, an area of disturbed weather that could not reliably be traced over the Atlantic was noted over Central America. A broad area of low pressure formed on the final day of July and moved west-northwest, gaining enough organization to be declared a tropical depression around 06:00 UTC on August 3. The depression turned northwest after formation tracked through an unfavorable wind shear environment. Despite this, it intensified into Tropical Storm Gil around 18:00 UTC on August 3, with the center located on the western edge of associated thunderstorm activity. Gil failed to intensify beyond minimal tropical storm intensity, losing its bursting convection as the storm encountered dry air. Gil degenerated to a remnant low around 00:00 UTC on August 5 well to the west-southwest of Baja California Sur. It dissipated the next morning.


2019 Pacific hurricane season, Systems, Tropical Storm Henriette
A vigorous tropical wave crossed the coastline of Africa on July 28 and moved west across the Atlantic. The wave nearly organized into a tropical depression over the eastern Caribbean Sea but soon lost organization. After it crossed into the East Pacific on August 9, subsequent interaction with a monsoon trough led to the formation of an area of low pressure, which continued on to become a tropical depression around 00:00 UTC on August 12 to the south of Baja California Sur. Increasing thunderstorm activity led to the designation of Tropical Storm Henriette six hours later. Henriette attained peak winds of 45 mph (70 km/h) before the combination of cooler waters and dry air caused weakening,  degenerating into a remnant low around 12:00 UTC on August 13 and dissipated two days later.


2019 Pacific hurricane season, Systems, Tropical Storm Ivo
Two tropical waves crossed the Atlantic in quick succession. The leading tropical wave spawned an area of low pressure over the eastern Pacific on August 6, while the second wave enhanced the low's convection. The disturbance gradually developed into a tropical depression by 06:00 UTC on August 21; it intensified into Tropical Storm Ivo six hours later. Favorable atmospheric conditions allowed Ivo to intensify over subsequent days, and it reached a peak intensity of 70 mph (115 km/h) early on August 22 as a mid-level eye became evident on microwave imagery.


2019 Pacific hurricane season, Systems, Tropical Storm Ivo
Although increasing wind shear caused it to slowly weaken, Ivo passed close to Clarion Island early on August 23, producing sustained winds of 61 mph (98 km/h) and gusts to 76 mph (122 km/h). The storm continued to weaken as it entered cooler waters. It degenerated to a remnant low around 06:00 UTC on August 25. The low meandered for a while before dissipating early on August 27 to the west of Baja California Sur.


2019 Pacific hurricane season, Systems, Hurricane Juliette
On August 18, a tropical wave moved off Africa. It inconspicuously crossed the Atlantic and emerged into the East Pacific on August 27. A broad area of low pressure formed in association with increased convective activity, leading to the formation of Tropical Storm Juliette by 00:00 UTC on September 1. The newly formed storm quickly organized amid favorable conditions, becoming a hurricane by 12:00 UTC on September 2 and entering a period of rapid intensification. Within a day, Juliette attained its peak at Category 3 intensity with winds of 125 mph (200 km/h). Beyond that time, the cyclone's eyewall collapsed and caused a persistent weakening trend. Juliette degenerated to a remnant low 06:00 UTC on September 7 to the west of Baja California Sur. The low drifted west and dissipated early on September 9.


2019 Pacific hurricane season, Systems, Tropical Storm Akoni
Early on September 4, the NHC began to track a quickly-developing area of low pressure about 1,100 mi (1,770 km) east-southeast of the Big Island of Hawaii. Just a few hours later, following a sudden increase in convection, the system organized into Tropical Depression Twelve-E and moved into the Central Pacific basin. It slowly intensified and eventually reached tropical storm status, whereupon it was named Akoni. The system struggled to organize because of high wind shear and quickly degenerated into a remnant low on September 6.


2019 Pacific hurricane season, Systems, Tropical Storm Akoni
Akoni is one of only seven tropical cyclones to form as a depression in the Eastern Pacific and be given a name in the Central Pacific, with the others being Lala in 1984, Iniki in 1992, Li in 1994, Lana in 2009, Ela in 2015 and Ulika in 2016.


2019 Pacific hurricane season, Systems, Hurricane Kiko
The final major hurricane of the season originated as a tropical wave that moved off Africa on August 27. It crossed into the East Pacific on September 7, where it spawned a tropical depression by 06:00 UTC on September 12. The depression intensified into Tropical Storm Kiko twelve hours later but struggled to organize further as it underwent multiple center reformations.


2019 Pacific hurricane season, Systems, Hurricane Kiko
Beginning at 00:00 UTC on September 14, however, Kiko entered a period of rapid intensification that brought the storm to its peak as a Category 4 hurricane with winds of 130 mph (210 km/h) a little over a day later. It displayed a prominent spiral band wrapping into a symmetric central dense overcast and large eye at that time. After reaching peak intensity, Kiko fluctuated in intensity due to varying atmospheric conditions while tracing a sinusoidal path across the Pacific. The storm finally lost its deep convection on September 24 and degenerated to a remnant low by 18:00 UTC as a result. The low turned west and dissipated on September 27.


2019 Pacific hurricane season, Systems, Hurricane Lorena
A large tropical wave departed Africa on September 4 and entered the East Pacific by September 16. The disturbance quickly organized upon emerging over water, and it became Tropical Storm Lorena at 06:00 UTC on September 17 while moving northwest. Lorena became a hurricane  on September 19 while passing very close to the coastline of Jalisco and made landfall near Chatmela-Cuixmala with winds of 75 mph (120 km/h) six hours later.


2019 Pacific hurricane season, Systems, Hurricane Lorena
Lorena weakened as it emerged back offshore, but it became a hurricane a second time and reached peak winds of 85 mph (135 km/h) late on September 20 as an eye appeared on satellite. The storm struck Baja California Sur near La Ventana at a slightly reduced strength at 03:00 UTC on September 21. Lorena weakened thereafter as it curved north, degenerating to a remnant low as it reached the coastline of mainland Mexico around 12:00 UTC on September 22 and dissipating six hours later.


2019 Pacific hurricane season, Systems, Tropical Storm Mario
A tropical wave, the same that spawned Tropical Storm Gabrielle in the Atlantic, left Africa on August 30 and progressed into the eastern Pacific on September 13. The wave led to the formation of a tropical depression around 12:00 UTC on September 17 and Tropical Storm Mario twelve hours later. Although Mario was located in close proximity to strengthening Tropical Storm Lorena and experienced shear from that storm's outflow, it still intensified to a peak of 70 mph (115 km/h) late on September 18 while weaving its way north across the Pacific. Shortly thereafter, upper-level winds increased further and caused a weakening trend that caused the system to degenerate to a remnant low by 00:00 UTC on September 23. The low moved parallel to the Baja California Sur before turning east and dissipating just west of the landmass late on September 24.


2019 Pacific hurricane season, Systems, Tropical Storm Narda
The deadliest tropical cyclone of the season originated as a tropical wave that left Africa on September 15. The wave entered the eastern Pacific on September 26, where it became embedded within the Intertropical Convergence Zone and organized. Tropical Storm Narda developed around 00:00 UTC on September 29 as a result. The nascent cyclone moved quickly northwest and made landfall northeast of Lázaro Cárdenas, Michoacán, at 14:00 UTC on September 29 harboring winds of 45 mph (70 km/h).


2019 Pacific hurricane season, Systems, Tropical Storm Narda
Mountainous terrain slightly weakened Narda as it crossed over land, but its large circulation and outside orographic effects aided in the maintenance of tropical storm-force winds. The storm immediately re-intensified once over water and attained peak winds of 50 mph (80 km/h) while developing a mid-level eye feature. Narda made a second landfall near Las Glorias around 00:00 UTC on October 1 at peak strength. It rapidly weakened after moving inland and dissipated six hours later over southern Sonora.

Narda brought heavy rains and flooding in southwestern Mexico. Two people were killed in Oaxaca, one in Colima, and one in Guerrero.


2019 Pacific hurricane season, Systems, Tropical Storm Ema
An area of low pressure developed a few hundred miles to the west of Hawaii on October 12. The system was assessed as having a low chance of development by the Central Pacific Hurricane Center; however, the system quickly organized later the same day. Gale-force winds soon developed, and consequently the CPHC upgraded the system to a tropical storm at 15:00 UTC, naming it Ema. Ema's existence was short-lived, however, as the storm weakened due to strong wind shear and degenerated to a remnant low on October 14.


2019 Pacific hurricane season, Systems, Tropical Storm Octave
An area of low pressure materialized within the monsoon trough across the eastern Pacific on October 15. The low drifted west-southwest and organized into a tropical depression around 12:00 UTC on October 17 before further intensifying into Tropical Storm Octave twelve hours later. The small storm attained peak winds of 45 mph (70 km/h) within a small central dense overcast before it drifted northward into an environment of dry air that prompted weakening. Octave degenerated to a remnant low around 18:00 UTC on October 19 as it curved east-northeast and later south-southwest. The remnant low dissipated two days later in the vicinity of where it first developed.


2019 Pacific hurricane season, Systems, Tropical Storm Priscilla
Another tropical wave moved off Africa on October 3 and fractured over the Caribbean Sea, with the northern portion spawning Tropical Storm Nestor in the Atlantic. The southern portion continued into the eastern Pacific, leading to the formation of a tropical depression around 00:00 UTC on October 20. It intensified into Tropical Storm Priscilla six hours later while turning north. Having spent little time over water, and affected by moderate easterly wind shear, Priscilla quickly moved into the coastline near Cuyutlán, Colima, at 19:30 UTC on October 20 as a minimal tropical storm. The cyclone weakened quickly once inland and dissipated by 06:00 UTC on October 21 over the rugged terrain of southwestern Mexico.


2019 Pacific hurricane season, Systems, Tropical Storm Priscilla
Priscilla and its precursor disturbance over Mexico caused heavy flooding and mudslides in and around areas Manzanillo.


2019 Pacific hurricane season, Systems, Tropical Storm Raymond
Yet another tropical wave left Africa on October 27. This feature entered the East Pacific on November 6, where it was enhanced by an ongoing Gulf of Tehuantepec gap wind event and an eastward-moving kelvin wave. The wave spawned a tropical depression by 12:00 UTC on November 14. It moved north and north-northwest while remaining largely disorganized in the presence of moderate northwesterly wind shear. By 06:00 UTC on November 15, the depression intensified into Tropical Storm Raymond. It attained peak winds of 50 mph (80 km/h) later that day before encountering increased wind shear from the southwest. Raymond slowly decayed and dissipated after 00:00 UTC on November 18 to the south of Baja California Sur.


2019 Pacific hurricane season, Systems, Tropical Storm Raymond
The remnants of the storm brought heavy rain to Southern California and Arizona, leaving over 13 million people under flash flood watch and alleviating unusually dry conditions, bringing the first significant rainfall to Southern California since May. The system also brought heavy snow to higher elevation areas.


2019 Pacific hurricane season, Systems, Tropical Depression Twenty-One-E
On November 2, a late-season tropical wave moved off the west coast of Africa. The wave entered the eastern Pacific on November 12 and spawned an area of low pressure the next day. A strong gap wind event kept the system disorganized as it passed south of the Gulf of Tehuantepec. Afterwards, deep convection began to develop closer to the center of the low, and the low's circulation became more apparent. This resulted in the formation of the season's final tropical depression around 00:00 UTC on November 16. Multiple center reformations and intrusions of dry air arrested development despite another favorable environment. This resulted in weakening, and the depression dissipated after 12:00 UTC on November 18.


2019 Pacific hurricane season, Systems, Other systems
A tropical wave entered the eastern Pacific by October 14, where it spawned a broad area of low pressure. The disturbance became better defined over the coming days, prompting the NHC to initiate advisories on Potential Tropical Cyclone Seventeen-E at 03:00 UTC on October 16 and facilitate tropical storm watches along the coastline of Mexico. The disturbance soon became poorly organized, as its convection dwindled and its center became less defined. The system moved inland between Bahias de Huatulco and Salina Cruz in the Mexican state of Oaxaca without ever having formed into a tropical cyclone. Gusty winds and heavy rain affected parts of El Salvador, causing significant damage. Four people died in storm-related incidents: three from flooding and one from a fallen tree. Eighty families required evacuation in Cangrejera.


2019 Pacific hurricane season, Storm names
The following names were used for named storms that form in the northeastern Pacific Ocean during 2019. This was the same list used in the 2013 season, with the exception of the name Mario, which replaced Manuel. The name Mario was used for the first time this year. No names were retired from this list, so all will be used again in the 2025 season.


2019 Pacific hurricane season, Storm names
For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists. The next four names that were slated for use in 2019 are shown below, though only two of them were used during the season.


2019 Pacific hurricane season, Season effects
This is a table of all the storms that have formed in the 2019 Pacific hurricane season. It includes their duration, names, affected areas, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a tropical wave, or a low, and all the damage figures are in USD. Potential tropical cyclones are not included in this table.


2019 Pacific typhoon season
The 2019 Pacific typhoon season was the costliest Pacific typhoon season on record, just ahead of the previous year. The season was fairly above-average, producing 29 named storms, 17 typhoons, and five super typhoons. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2019, though most tropical cyclones typically develop between May and October.


2019 Pacific typhoon season
The season's first named storm, Pabuk, reached tropical storm status on January 1, becoming the earliest-forming tropical storm of the western Pacific Ocean on record, breaking the previous record that was held by Typhoon Alice in 1979. The season's first typhoon, Wutip, reached typhoon status on February 20. Wutip further intensified into a super typhoon on February 23, becoming the strongest February typhoon on record, and the strongest tropical cyclone recorded in February in the Northern Hemisphere. The season's last named storm, Phanfone, dissipated on December 29 after it made landfall in the Philippines. The accumulated cyclone energy (ACE) index of this season amounted to 269 units.


2019 Pacific typhoon season
Another notable storm, Typhoon Lekima, became the second-costliest typhoon in Chinese history, behind Typhoon Fitow of 2013. Typhoon Hagibis became one of the costliest tropical cyclones in Japanese history. Typhoon Halong became the strongest typhoon of the season and also the strongest tropical cyclone worldwide in the year. Two of these cyclones, Lekima and Hagibis, as well as another notable storm, Typhoon Faxai, were responsible for a majority of the catastrophic damage attributed to the season, with $32.4 billion just by those three tropical cyclones. Typhoon Mitag was also responsible for nearly a billion in damage, adding up to $816 million.


2019 Pacific typhoon season
The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian. Within the northwestern Pacific Ocean, two separate agencies assign names to tropical cyclones which can often result in a cyclone having two names.


2019 Pacific typhoon season
The Japan Meteorological Agency (JMA) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, while the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E–115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) are given a number with a "W" suffix.


2019 Pacific typhoon season, Seasonal forecasts
During the year, several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA and Taiwan's Central Weather Bureau. The first forecast of the year was released by PAGASA on February 7, within its seasonal climate outlook for the period January–June.


2019 Pacific typhoon season, Seasonal forecasts
The outlook noted that one to two tropical cyclones were expected between January and March, while two to four were expected to develop or enter the Philippine Area of Responsibility between April and June. Moreover, PAGASA predicts an 80% chance of a weak El Niño presence during February–March–April period. On May 7, the TSR issued their first forecast for the season, predicting that the 2019 season would be a slightly above average season, producing 27 named storms, 17 typhoons, and ten intense typhoons. One of the factors behind this is due to the possible development of a moderate El Niño anticipated within the third quarter of the year.


2019 Pacific typhoon season, Seasonal forecasts
On July 5, the TSR released their second forecast for the season, now lowering their numbers and predicting that the season would be a below-average season with 25 named storms, 15 typhoons, and eight intense typhoons. The PAGASA issued their second forecast for the season on July 15, predicting six to nine tropical cyclones expected to develop or enter their area between July and September and about three to five tropical cyclones by September to December. The agency also predicted that the weak El Niño was expected to weaken towards neutral conditions by August and September 2019. On August 7, the TSR released their final forecast for the season, predicting a near-normal season with 26 named storms, 16 typhoons and eight intense typhoons.


2019 Pacific typhoon season, Season summary
This year's season had a slightly-above average season. It featured 52 tropical cyclones, 29 named storms, 17 that became typhoons and four became super typhoons. Throughout the storm, there were at least 388 deaths from several storms, the least deadly since 2015 season and with a record of $34.14 billion in damages becoming the costliest Pacific typhoon season on record, only surpassing with the previous season.


2019 Pacific typhoon season, Season summary
The first half of the season was considerably inactive, opening up with Tropical Depression Usman from 2018 season active just to the south of Vietnam. The system, shortly thereafter, strengthened into Tropical Storm Pabuk, which became the first named storm of the season. Four days later, Pabuk make landfall in Thailand and exited the basin and into the Bay of Bengal. In that same month, Tropical Depression 01W (Amang) affected eastern Philippines bringing torrential rainfall.


2019 Pacific typhoon season, Season summary
The next named storm, Typhoon Wutip, strengthened into a Category 5-equivalent super typhoon and became the most powerful February typhoon on record, surpassing Typhoon Higos in 2015. Several tropical depressions have developed during the months from March through to May, however none have strengthened into named storms. The month of June was unusually quiet with the next named storm, Sepat, only peaking as a tropical storm, affected mainland Japan bringing gusty winds and a tornado. Tropical Storm Sepat, however, was only classified as a subtropical storm by the JTWC.


2019 Pacific typhoon season, Season summary
On July, four named storms developed and affected land: Mun, which affected South China, Danas and Nari, which affected mainland Japan, and Wipha which also affected South China. None of the storms, however, reached typhoon intensity, which is very rare for the month of July. By August, tropical activity began to increase with the development of three simultaneous typhoons. Typhoon Francisco affected Japan and the Korean Peninsula. Typhoon Lekima reached Category 4-equivalent super typhoon intensity east of Taiwan and made landfall in Zhejiang of eastern China.


2019 Pacific typhoon season, Season summary
Lekima brought total damages of $9.28 billion, making it the fifth costliest typhoon and the costliest typhoon in China. Typhoon Krosa formed as a Category 3 typhoon and made landfall in Japan as a severe tropical storm. Tropical Storms Bailu and Podul impacted Taiwan and the Philippines respectively as well as southern China but caused minimal damage.

2019 Pacific typhoon season, Season summary
In the month of November, six named storms were recorded, including the most intense tropical cyclone of the season, Halong, formed on November 1 and became to intensify as a Category 5 super typhoon four days later with 10-minutes sustained winds of 215 km/h (130 mph) and with a minimum pressure of 905 millibars. In late-November, another storm formed that was named Kammuri on November 24. Kammuri became intensified as a Category 4 typhoon on the Saffir-Simpson Wind Scale, Kammuri made landfall in Philippines on November 30 confirming twelve people who died from the storm, with $116 million in damage.


2019 Pacific typhoon season, Season summary
The month of December had a quiet activity, after Kammuri's landing in Philippines, the arrival of the last named storm of the season, Phanfone, formed on December 19. Phanfone made landfall in the Philippines on December 25 during Christmas Eve as a Category 2 typhoon, the first time since Typhoon Nock-ten in 2016. Phanfone dissipated on December 29 after making landfall in Philippines, leaving a total of 50 deaths and with $61.7 million in damages.


2019 Pacific typhoon season, Systems
Also, windspeed advisories differ from the Joint Typhoon Warning Center to the Japan Meteorological Agency as the JTWC uses the U.S. criteria of 1 minute mean to designate maximum sustained winds, while the JMA uses the 10-minute mean wind criteria to designate tropical cyclone maximum sustained winds. This difference generally means that JTWC maximum winds will appear to be higher than the maximum winds described by the JMA for the same cyclone.


2019 Pacific typhoon season, Systems, Tropical Storm Pabuk
A tropical disturbance formed over the southern portion of the South China Sea on December 28, 2018, which absorbed the remnants of Tropical Depression 35W (Usman) on December 30. Under high vertical wind shear, the low-pressure area remained disorganized until December 31 when it was upgraded to a tropical depression by both the JMA and the JTWC. As it was designated 36W by the JTWC, it was unofficially the last system of the 2018 typhoon season.


2019 Pacific typhoon season, Systems, Tropical Storm Pabuk
At around 06:00 UTC on January 1, 2019, the system was upgraded to the first tropical storm of the 2019 typhoon season and named Pabuk by the JMA, surpassing Typhoon Alice in 1979 to become the earliest-forming tropical storm of the northwest Pacific Ocean on record. At that time, Pabuk was about 650 km (405 miles) southeast of Ho Chi Minh City, Vietnam and drifted westward slowly with a partially exposed low-level circulation center.


2019 Pacific typhoon season, Systems, Tropical Storm Pabuk
Under marginal conditions including warm sea surface temperatures, excellent poleward outflow but strong vertical wind shear, Pabuk struggled to intensify further for over two days until it accelerated west-northwestward and entered the Gulf of Thailand on January 3, where vertical wind shear was slightly weaker. It became the first tropical storm over the gulf since Muifa in 2004. Moreover, it tried to form an eye revealed by microwave imagery.


2019 Pacific typhoon season, Systems, Tropical Storm Pabuk
On January 4, the Thai Meteorological Department reported that Pabuk had made landfall over Pak Phanang, Nakhon Si Thammarat at 12:45 ICT (05:45 UTC), although other agencies indicated a landfall at peak intensity between 06:00 and 12:00 UTC. Pabuk became the first tropical storm to make landfall over southern Thailand since Linda in 1997. Shortly after 12:00 UTC, the JMA issued the last full advisory for Pabuk as it exited the basin into the North Indian Ocean.


2019 Pacific typhoon season, Systems, Tropical Storm Pabuk
In Vietnam, Pabuk caused one death, and the losses were estimated at ₫27.87 billion (US$1.2 million). Eight people in Thailand were killed, and the losses in the country were estimated to be 5 billion bahts (US$156 million). Pabuk also killed one person in Malaysia.


2019 Pacific typhoon season, Systems, Tropical Depression 01W (Amang)
The JTWC upgraded a disturbance north of Bairiki to a tropical depression with the designation 01W late on January 4 and expected some intensification, but it failed to develop and the JTWC downgraded it back to a disturbance on January 6. The system continued drifting westwards for two weeks without development. On January 19, the JMA upgraded the low-pressure area to a tropical depression when it was already located about 200 km (120 mi) west of Palau. The tropical depression entered the Philippine Area of Responsibility, being given the name Amang by PAGASA.


2019 Pacific typhoon season, Systems, Tropical Depression 01W (Amang)
Amang moved west-northwestward until it made landfall over Siargao at 11:00 Philippine Standard Time (PST), January 20. Amang changed course after the landfall, turning northward the next day until weakening over Samar the same day. Amang then weakened into a low pressure area before dissipating shortly afterwards, which then PAGASA issued their final advisories.


2019 Pacific typhoon season, Systems, Tropical Depression 01W (Amang)
The depression indirectly triggered landslides and flash floods in Davao Oriental and Agusan del Norte, killing 10 people. Damage in Davao were at ₱318.99 million (US$6.04 million).


2019 Pacific typhoon season, Systems, Typhoon Wutip (Betty)
A low-pressure area formed just south of the Marshall Islands on February 16. It then began to gradually organize while moving westward, just south of Federated States of Micronesia. The system was upgraded to a tropical depression by the JMA on February 18, with the JTWC following suit on the following day, assigning the storm the identifier 02W. On February 20, the tropical depression intensified into a tropical storm and received the name Wutip from the JMA. On February 21, Wutip strengthened into a severe tropical storm, before intensifying further into a typhoon later that day.


2019 Pacific typhoon season, Systems, Typhoon Wutip (Betty)
On February 23, Wutip intensified further, reaching its peak intensity as a Category 5-equivalent super typhoon with maximum 10-minute sustained winds of 195 km/h (120 mph), 1-minute sustained winds of 270 km/h (165 mph), and a minimum pressure of 920 hPa (mbar), while passing to the southwest of Guam, surpassing Typhoon Higos from 2015 as the strongest February typhoon on record. Wutip underwent an eyewall replacement cycle shortly thereafter, weakening in intensity as it did so while turning to the northwest.


2019 Pacific typhoon season, Systems, Typhoon Wutip (Betty)
The typhoon finished its eyewall replacement cycle on February 24 and resumed strengthening; early on February 25, Wutip reached its second peak intensity as a Category 5-equivalent super typhoon, with maximum 10-minute sustained winds of 185 km/h (115 mph), 1-minute sustained winds of 260 km/h (160 mph), and a minimum central pressure of 935 hPa (27.6 inHg). This made Wutip the first Category 5-equivalent super typhoon recorded in the month of February. This also made Wutip the strongest typhoon ever recorded in February in the Northern hemisphere.


2019 Pacific typhoon season, Systems, Typhoon Wutip (Betty)
On February 26, Wutip entered a hostile environment with moderate wind shear and began to weaken, concurrently making another turn westward. On February 28, Wutip weakened into a tropical depression and lost most of its convection. On the same day, Wutip was given the name "Betty" by the PAGASA as the storm entered the Philippine Sea. Soon afterward, Wutip entered a more hostile environment, with very high vertical wind shear (40–50 knots or 74–93 km/h or 46–58 mph) and lower sea surface temperatures, and the storm rapidly weakened until it dissipated on March 2.

Preliminary estimates of damage in Guam and Micronesia were at $3.3 million.


2019 Pacific typhoon season, Systems, Tropical Depression 03W (Chedeng)
On March 14, Tropical Depression 03W formed over the Federated States of Micronesia. Over the next couple of days, the system drifted westward, while gradually organizing. Early on March 17, the tropical depression entered the PAGASA's area of responsibility in the Philippine Sea, and consequently, the agency assigned the name Chedeng to the storm, shortly before it made landfall on Palau. Very few hours after the landfall in Palau, Chedeng intensified into a tropical storm, but it was soon, as it weakened due to unfavorable conditions for an intensification. At 5:30 PST on March 19, Chedeng made landfall on Malita, Davao Occidental. Chedeng rapidly weakened after making landfall in the Philippines, degenerating into a remnant low on March 19. Chedeng's remnants continued weakening while moving westward, dissipating over the southern Sulu Sea on March 20.

Operationally, Chedeng was classified as a tropical depression, but in the re-analysis it was upgraded to tropical storm by the JTWC.


2019 Pacific typhoon season, Systems, Tropical Storm Sepat (Dodong)
On June 24, the JMA began monitoring on a tropical depression that had formed well to the east of Luzon from the remnants of a separate system. On June 25, the system began curving towards the northeast; the PAGASA also began to issue warnings on the formative disturbance. Rounding the periphery of a subtropical ridge of high pressure, the depression tracked towards the east-northeast through the East China Sea, intensifying some as it encountered an area of high sea surface temperatures and low wind shear. On June 26, the cyclone left the PAGASA's area of responsibility.


2019 Pacific typhoon season, Systems, Tropical Storm Sepat (Dodong)
Curved banding developed later that day as the center passed east of Okinawa. Tracing the northwestern periphery of the ridge, the system curved towards the east-northeast, paralleling the southern coast of the main Japanese islands. Supported by favorable sea surface temperatures and outflow, the system was upgraded to a tropical storm at 09:00 UTC on June 27, gaining the name Sepat. A peak intensity with 75 km/h (47 mph) 10-minute sustained winds was attained later that day while Sepat began to acquire extratropical characteristics. The next day, the storm fully transitioned into an extratropical system while accelerating eastward 580 km (360 mi) east of Hitachinaka, Japan. Sepat's extratropical remnants continued accelerating towards the northeast, moving into the western Bering Sea on July 1, before eventually dissipating over the Arctic Ocean early on July 5.


2019 Pacific typhoon season, Systems, Tropical Storm Sepat (Dodong)
This system was not tracked by the JTWC; however, the agency classified the system as a subtropical storm, with 1-minute sustained winds at 75 km/h (45 mph). Some ferry routes and bullet trains were suspended as the storm passed near Tokyo on June 28, dropping heavy rainfall. Evacuations were advised for most districts in Kagoshima due to an increased risk of landslides. In Hioki, Kagoshima, 164 mm (6.5 in) of rain fell in a six-hour period on the morning of June 28; 240 mm (9.4 in) fell in Kamikatsu, Tokushima, in a 24-hour period. An EF0 tornado damaged 17 structures in Gifu and Ginan.


2019 Pacific typhoon season, Systems, Tropical Depression 04W (Egay)
Tropical Depression 04W, known as Egay in the Philippines, formed on June 27 and slowly tracked northwestward before dissipating on July 1. This storm did not affect land other than moderate wind gusts and moderate rainfall.


2019 Pacific typhoon season, Systems, Tropical Storm Mun
On July 1, an area of low pressure organized into a tropical depression formed in the South China Sea, near Hainan and the Paracel Islands. The system gradually organized while drifting eastward. On the next day, the tropical depression strengthened into a tropical storm, and the JMA named the storm Mun. Later that day, Tropical Storm Mun made landfall on the island of Hainan. However, the JTWC still recognized Mun as a monsoon depression and didn’t upgrade it into a tropical cyclone for another day.


2019 Pacific typhoon season, Systems, Tropical Storm Mun
Late on July 3, after the storm had nearly crossed the Gulf of Tonkin to the coast of Vietnam, the JTWC upgraded the storm to tropical storm status and initiated advisories on the system, stating that Mun had organized enough to be considered a tropical cyclone. Between 4:30–5:00 a.m. ICT on July 4 (21:30–22:00 UTC on July 3), Mun made landfall in Thái Bình Province in northern Vietnam. Afterward, Mun moved inland while weakening, before dissipating late on July 4.

A bridge in Tĩnh Gia District was damaged by the storm, which killed 2 people and left 3 injured. Damage of an electric pole in Trấn Yên District were at ₫5.6 billion (US$240,000).


2019 Pacific typhoon season, Systems, Tropical Storm Danas (Falcon)
On July 12, an area of low pressure formed near the Mariana Islands. During the next couple of days, the system slowly drifted westward while gradually organizing. Early on July 14, the low-pressure area organized into a tropical depression to the southwest of the Mariana Islands. Later that day, the tropical depression entered the Philippine area of responsibility, and the PAGASA gave the system the name Falcon. Afterward, the system continued organizing while approaching Luzon. On July 16, the tropical depression strengthened into a tropical storm, and the JMA named the system Danas.


2019 Pacific typhoon season, Systems, Tropical Storm Danas (Falcon)
Shortly afterward, at 12:00 UTC that day, the JTWC upgraded Danas to a tropical storm. At 12:30 a.m. on July 17 (PST), PAGASA reported that Danas (Falcon) had made landfall at Gattaran, Cagayan and looped over the landmass. However, Danas's center of circulation still remained off the coast of Luzon, and the JMA and JTWC both stated that Danas did not make landfall at all. Northeasterly wind shear had displaced much of Danas' convection to the west, and an area of low pressure had formed to the east of Luzon.


2019 Pacific typhoon season, Systems, Tropical Storm Danas (Falcon)
This led to the formation of another area of low pressure over the western Philippines. This low would later develop into Tropical Depression Goring. On July 19, the JMA reported that Danas has reached its peak intensity with winds of 85 km/h (50 mph). Later that day, Danas began to weaken. On July 20, around 13:00 UTC, Danas made landfall on North Jeolla Province, South Korea, before weakening into a tropical depression soon afterward. At 12:45 UTC on July 21, Danas transitioned into an extratropical low in the Sea of Japan, and the JMA issued their final advisory on the storm.


2019 Pacific typhoon season, Systems, Tropical Storm Danas (Falcon)
In Philippines, four people were killed after Danas triggered flooding in the country. Agricultural damage in Negros Occidental were calculated at ₱19 million (US$372,000), while agricultural damage in Lanao Norte reached ₱277.8 million (US$5.44 million). Danas caused stormy weather across South Korea; however, its effects were relatively minor. Heavy rains amounted to 329.5 mm (12.97 in) in Geomun-do. A man died after being swept away by strong waves in Geochang County. Damage in South Jeolla Province were at W395 million (US$336,000), while damage in Jeju Island up to W322 million (US$274,000). Additionally, Danas also triggered flash flooding in Kyushu. An 11-year-old boy was killed.


2019 Pacific typhoon season, Systems, Tropical Depression Goring
On July 17, a tropical depression formed from the western part of Tropical Storm Danas after it was battered by northeast wind shear, over the eastern part of the South China Sea, just off the coast of Luzon. Over the next couple of days, the system moved northeastward, and re-entered the PAGASA's Philippine Area of Responsibility, and was named Goring while the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on Goring. Goring reached southern Taiwan early on July 19.


2019 Pacific typhoon season, Systems, Tropical Depression Goring
However, the storm made landfall on Taiwan soon afterward and weakened; as a result, the JTWC cancelled the TCFA and has lowered Goring's chance for development to 'medium'. Goring dissipated by 18:00 UTC on July 19 (July 20 PST), with PAGASA declaring that Goring had degenerated into a low-pressure area and discontinued advisories on the storm, and the JMA ceased advisories as well. The remnant of Goring was then merged with a new low pressure system which would eventually become a Tropical Storm Nari. Goring's outflow was then re-absorbed by Danas.


2019 Pacific typhoon season, Systems, Tropical Storm Nari
On July 21, the JTWC started tracking an area of low pressure associated with remnant of Tropical Depression Goring for the potential formation of a tropical cyclone. Under favorable conditions, the system organized itself in the next several days. At 00:00 UTC on July 24, it developed into a tropical depression to the west of the Bonin Islands. The storm gradually became more organized while moving north-northwestward. Early on July 25, the JTWC initiated advisories on the storm and gave it the identification "07W".

On September 14, a tropical depression formed. The Joint Typhoon Warning Center later issued a Tropical Cyclone Formation Alert and as it gradually developed, it was given the designation 17W. Despite the high wind shear, the depression soon intensified to a tropical storm and was named Peipah. Peipah sustained itself for 12 hours before weakening again into a tropical depression according to the Joint Typhoon Warning Center. Tropical Storm Peipah later succumbed to the wind shear, weakening into a remnant low.


2019 Pacific typhoon season, Systems, Typhoon Tapah (Nimfa)
On September 17, a tropical depression formed from the remnants of Tropical Depression Marilyn east of Batanes. PAGASA later named the tropical cyclone as "Nimfa", as the JTWC issued a medium warning for Nimfa. Tropical Depression Nimfa was later given a Tropical Cyclone Formation Alert but still classified it as a monsoon depression by JTWC. The JTWC later designated Nimfa as 18W. Tropical Depression Nimfa was upgraded by the Japan Meteorological Agency into a tropical storm, and was named Tapah. A non-warning tropical depression in the South China Sea merged with the circulation of Tapah on Thursday, September 19. Tapah still had a disorganized and mostly exposed center on September 19. Tapah later re-organized itself, and further intensified into a severe tropical storm.
